Question

The LCM of the two numbers is 432 and their HCF is 72. If one of the numbers is 144, the other number is:
1. 125
2. 343
3. 324
4. 216

Answer 1

Correct Answer - Option 4 : 216

Given:

The LCM of two numbers = 432 and their HCF = 72

And one number 144

Formula used:

We know that formula, first number × second number = LCM × HCF

Calculation

Required numbers = (LCM × HCF) ÷ One numbers

Then Required numbers = (432 × 72) ÷ 144

Required numbers = 216
